    <p>1000 kg. CO<sub>2</sub> emissions per year per capita for various countries (source: <a href="http://en.wikipedia.org/wiki/List_of_countries_by_carbon_dioxide_emissions_per_capita">Wikipedia</a>).</p>

    <p>Flot supports selections through the selection plugin.
       You can enable rectangular selection
       or one-dimensional selection if the user should only be able to
       select on one axis. Try left-click and drag on the plot above
       where selection on the x axis is enabled.</p>

    <p>You selected: <span id="selection"></span></p>

    <p>The plot command returns a plot object you can use to control
       the selection. Click the buttons below.</p>

    <p><input id="clearSelection" type="button" value="Clear selection" />
       <input id="setSelection" type="button" value="Select year 1994" /></p>

    <p>Selections are really useful for zooming. Just replot the
       chart with min and max values for the axes set to the values
       in the "plotselected" event triggered. Enable the checkbox
       below and select a region again.</p>

    <p><label><input id="zoom" type="checkbox" />Zoom to selection.</label></p>
